Overview
Although the state of Minnesota requires you to earn two hours of ethics credit each renewal cycle, they do not require a specific course. Any of the courses in our Ethics category will meet the Minnesota requirement, but each year we select one of our most popular courses as our Minnesota Ethics Course of the Year. This course is guaranteed to meet the ethics requirement in your state and in any other with an ethics requirement. So, we hope you enjoy meeting your ethics requirement with this year’s selection,Engineering Ethics: The Minnesota I-35W Bridge Collapse.


In Engineering Ethics: The Minnesota I-35W Bridge Collapse, you'll learn ...

  • The original bridge design and design errors that led to the disaster
  • The important role of quality control procedures for designing, reviewing, and approving bridge design plans and calculations
  • The responsibilities of engineers as they relate to public safety, regulatory authorities, and liability issues

On August 1, 2007, the I-35W Bridge over the Mississippi River in Minneapolis, Minnesota, collapsed during the evening rush hour, plummeting into the river and onto the concrete embankment below. At the time of the collapse, traffic was congested from both usual rush hour traffic as well as fans headed to the Twins game. In some places, the cars were bumper to bumper, their progress constrained by two lanes closed for construction. In all, 111 vehicles were on the collapsed part of the bridge, along with members of the construction crew working on the bridge with their equipment and supplies. The disaster killed 13 people and injured 145 more, and the loss of an important interstate bridge had a major impact on the Minneapolis economy.

Perhaps one of the most striking things about the Minneapolis I-35W bridge collapse is that an engineer made a critical error in the design of a steel truss bridge more than 40 years before the disaster, which means that for more than 40 years, the error and the symptoms of the impending failure of the bridge component were never properly identified or addressed. Not one member of a quality control team or any safety system in place at the time addressed the source of the error or heeded the warning signs of the impending disaster. Despite state and federal guidelines and regulations, the Minnesota Department of Transportation (Mn/DOT), Mn/DOT inspectors, and engineering groups hired to inspect the bridge all failed to act. As a result, the engineering design and inspection firms, the construction company working on the bridge at the time of collapse, and the State of Minnesota all faced enormous liability issues.

This course reviews the analyses made by the National Transportation and Safety Board (NTSB) and other sources in order to familiarize the reader with the design errors that led to the disaster. It also examines the failures of the quality control process, insufficient bridge inspections, and deficiencies within the state and federal specifications and guidelines that caused the impending failure of the bridge connectors to be overlooked for more than 40 years after the initial design. The webinar will also discuss the responsibilities of engineers as they relate to public safety, regulatory authorities, and liability issues.

Special Note: Course ET-2011, ET-2015W, and ET-2034 are alternate presentations of the same course material. Therefore, only one version, either the course or webinar, can be taken during a renewal cycle. If you have any questions regarding course eligibility, please contact our Customer Service Team.
